Between a still-damp camera bag, the deck of a boat, and the hours of transfer time between dives, some equipment choices are made less by reading a technical specification sheet and more by the moment when you really need to rely on them. Underwater photographers often seek to reduce the volume of their luggage without sacrificing the security of their workflow. It is in this context of seeking versatility that the Anker 733 GaNPrime, also known as model A1651, finds its place by offering a unique hybrid architecture [1].
The idea of merging a wall charger and a power bank reaches an interesting level of technical maturity thanks to GaNPrime technology. This component allows for high thermal efficiency while reducing the device's dimensions to 111 x 63 x 31 mm [2]. For those preparing for a liveaboard trip, this accessory advantageously replaces two separate items in the technical kit.The housing features a refined finish and a density that inspires confidence in its build quality. Weighing in at 320 grams, it's easily forgotten in a backpack pocket or a carry-on suitcase. This 2-in-1 design means that as soon as you find a power outlet in your cabin, the device functions as a powerful charger while also replenishing its own power reserve.
When plugged into a power outlet, the Anker 733 unlocks its full potential. It delivers a maximum power of 65W via its two USB-C ports [2]. This performance allows you to directly power a MacBook Air or a PC laptop that is compatible with the Power Delivery 3.0 protocol. For a photographer who needs to download memory cards and begin the initial sorting of their images, this power ensures that the computer will not lose battery life during the process.
The power distribution is intelligently managed. If you connect multiple devices, the system adapts the output to optimize the charging speed. You can therefore charge a smartphone and a hybrid camera battery simultaneously without significantly increasing the charging time. This versatility in stationary mode is a major advantage of this model.
The nominal capacity is 10,000 mAh [1]. In practice, this provides approximately two full charge cycles for a standard mirrorless camera battery. This is not a power station designed for several days of autonomy, but rather a safety net for transfers or intense diving days.
On the deck of a boat or in the hustle and bustle of a dive center, the ergonomics of an accessory are more important than its raw power. The Anker 733 has three ports: two USB-C and one 22.5W USB-A [2]. This configuration covers almost all current needs, from modern cables to older standards found on some accessories like focus lights.
The LED system on the front allows you to easily monitor the remaining charge level. This device consumes very little power and remains functional in bright light. GaNPrime technology plays a crucial role here by preventing excessive heat, even when the device is being used at its maximum capacity as a wall charger.
Carrying spare batteries in checked baggage is strictly prohibited. Your battery must travel with you in the cabin. This precaution is important because the regulations of the airline and the relevant authority always take precedence over general recommendations. Therefore, the term "compliant" for this device is conditional on verifying the specific rules of your airline at the time of travel.
This model is designed for the traveler who wants to optimize every square centimeter of their bag. If your equipment includes a smartphone, a tablet, and a hybrid camera housing, the Anker 733 can be your only charging solution. It simplifies logistics by eliminating the need to carry a separate power adapter and a standard external battery.It is particularly suitable for photographers using cameras whose batteries are rechargeable via USB-C. Keeping it in your dive bag provides a reserve that can bring your camera housing back to life between dives, while you know you can quickly recharge it once you return to your accommodation.
The Anker 733 is not a universal product. Its 36 Wh capacity remains modest compared to models with 20,000 mAh. For a user planning long trips without access to a power outlet, it may prove insufficient. The power drop to 30 W in battery mode is also a factor to consider if you plan to primarily use it to power a laptop on the go.
| Feature | Technical Value | AquaExposure Observation | |
|---|---|---|---|
| Capacity | 10,000 mAh (36 Wh) | Ideal backup for 2 camera charges | |
| AC Output | 65 W (USB-C) | Sufficient power for a MacBook Air | |
| Battery Output | 30 W (USB-C) | Slow charging for laptops | |
| Weight | 320 g | Excellent portability for travel | |
| Ports | 2x USB-C, 1x USB-A | Complete versatility for accessories | AquaExposure scores, editorial guidelines to help you make your choices, place this device at the top for its balance of versatility and size. These scores should not be interpreted as the results of laboratory tests, but rather as an assessment of the object's relevance in real-world use. For an underwater photographer, reliability often takes precedence over extreme theoretical performance. |
The Anker 733 GaNPrime succeeds in its goal of simplification. By combining two essential functions in a compact size, it meets a concrete demand for lightness and efficiency. It is not the most powerful battery on the market, but it is likely one of the smartest for those who refuse to be weighed down by unnecessary equipment.
When equipment stops demanding your attention with a tangle of cables, you can finally focus on what brought you there. A change in the light on the reef, a moment of silence at depth, and that simple desire to return to the water with equipment ready to capture the moment.

Yes, when used with a wall charger, it delivers 65W, which is sufficient for a MacBook Air or a compatible PC. In battery mode, the power drops to 30W, which allows for slow charging or helps to extend battery life.
With an energy output of 36 Wh, it is well below the 100 Wh limit set by IATA. It must be transported in the passenger cabin. While airline regulations are always the final authority, it is recommended to verify the requirements before your departure.
Its 10,000 mAh capacity allows for approximately two full charges of a standard hybrid camera housing battery, making it an excellent backup solution between dives.
